Abstract
To facilitate the user installation of units in a computer, a clamping lever arrangement
(2) is provided which can be tightened up by an external screw to clamp in position one
or more units internal to the housing. In one arrangement, the clamping lever (22) is
provided with four fingers (26) that pass through respective apertures (32) in the
computer housing (31). Each finger (24) serves to clamp in position a respective
expansion card (10), or blanking plate (20) if no card is present. Thus a single
clamping lever (22) with a single external fixing screw (25) replaces the standard usage
of a respective fixing screw for each card.
Description
The present invention relates to an arrangement for securing a user-installable unit
(such as a plug-in expansion card or disc drive unit) inside a computer housing.
Figure 1 of the accompanying drawings illustrates a standard plug-in expansion card
10 for a computer. The card 10 carries electronic circuitry (not shown) intended to
connect with the main computer circuitry through a plug-in edge connector portion 11.
Plugging in the card 10 by its connector portion 11 into a connector of the computer
serves to locate the card in the computer. However, to retain the card in position and
hold it fast, the card is further provided at one end with a metal mounting plate 12.
This plate has locating tab 13 at one end and a screw-receiving recess 14 at the other
end. The plate may be apertured to enable external acces to external connectors
mounted on the expansion card.
Figure 2 shows a typical computer housing structure 15 in the region of mounting of
expansion cards inside the computer. In particular, a metal mounting bridge 16 is
provided which is adapted to support up to four expansion cards. The mounting bridge
16 is provided with four threaded apertures 17 for receiving fixing screws, one for
each expansion card to be secured in position. In addition, the bridge 16 is formed with
four rectangular apertures 18, each permitting access to any external connectors
provided on an expansion card.
Figure 3 shows the mounting of two expansion cards 10 on the mounting bridge 16 of
the Figure 2 structure 15. The expansion cards are first plugged by their connector
portions into internal electrical connectors mounted on a circuit board extending out at
right angles from the housing wall (neither this circuit board nor the connectors are
shown as the present invention is not concerned with these elements). At the same
time, the locating tab 13 of each card is inserted in a corresponding slot formed in the
housing structure (again, this slot is not shown as it is not relevant to the invention).
The mounting plate 12 of each card lies against the mounting bridge with the recess
14 of each mounting plate aligned with a corresponding one of the threaded apertures
18 in the mounting bridge 16. A fixing screw 19 is then used to secure each card in
position, the screw being engaged in the corresponding aperture 18 and screwed down
to clamp the mounting plate of the card against the bridge 16. This clamping also
serves to provide a good grounding (earthing) connection between the plate 12 and the
mounting bridge 16.
This prior art arrangement for securing expansion cards in position is somewhat
cumbersome for unskilled users who may drop the fixing screws inside the computer
or may find it difficult to screw in the screws 19 (the close presence of the housing
hindering turning of the screws by hand). The need to have multiple fixing screws
where multiple expansion card slots are present is also inconvenient.
Figure 4 shows one known arrangement for overcoming some of the problems
presented by the traditional way of securing expansion cards in position. In the Figure
4 arrangement, a clamping bar 40 provided with clamping fingers 41 is used to secure
in position a plurality of expansion cards / blanking plates (for reasons of clarity, only
one card 10 is illustrated). More particularly, the fingers 41 serve to clamp the card
mounting plates 12 / blanking plates against a bridge structure 16 of the housing 15.
At each end of the clamping bar 40 is a side pillar 42 that supports the bar on the top
of the bridge structure 16. Each pillar 42 has a depending spigot 43 that is located in
an aperture 44 in the bridge structure 16. The spigots 43 serve to position the bar and
to define an axis A about which the bar can be pivoted in a direction indicated by
arrow B to move the bar 40 from an inclined position (in which it resides when the
spigots are first introduced into the apertures 44) to an upright position shown in
Figure 4. In the latter position, a snap-engagement member 45 provided on top of the
bar 40, snap engages in an aperture 46 formed in the housing 15. In use, once the card
10 has been placed in position, the spigots of the clamping bar 40 are inserted into the
apertures 44 and the bar is then pivoted into its upright position to move a
corresponding one of the fingers into clamping engagement with the mounting plate 12
of card. When upright, the bar 40 snap engages into position. The bar 40 is made of
a plastics material and in order to facilitate electrical grounding of the mounting plate
12, a thin metal grounding finger can be provided beneath each finger 41, these
grounding fingers being electrically connected to a contact that is pressed against the
housing when the bar is in its snap-engaged position.
Although the Figure 4 arrangement facilitates the secural of multiple cards and avoids
the risk of fixing screws being lost inside the housing, a number of drawbacks still
exist. Thus, the need to provide side pillars to support pivoting movement of the bar
means that the extent of the mounting bridge is greater than otherwise needed - this
makes the arrangement unsuitable for use where space is at a premium (for example,
it would be difficult to use the arrangement in the Figure 2 situation). Furthermore, the
magnitude of clamping pressures obtainable using the Figure 4 arrangement is generally
not as great as can be achieved with a screw mechanism which also has the benefit of
adjustability. Finally, the need to provide a complex plastics part (the bar 40) and a
separate metal grounding part, increases the cost of the securing arrangement.
It is an object of the present invention to provide an arrangement for securing an
expansion card (or other user-installable unit) that overcomes at least some of the
disadvantages of the prior art.
According to the present invention, there is provided an arrangement for securing a
user-installable unit inside a computer housing, the arrangement comprising:
The user-installable unit is, for example, a plug-in expansion card, a disc drive unit or
other functional unit; however, the term "user-installable unit" is also to be construed
to cover a blanking plate for closing an access aperture in the computer housing.
Advantageously, the clamping lever has a plurality of internal fingers connecting to
said external arm, these fingers serving to secure a plurality of user-installable units
by clamping them against the housing. Preferably, the fingers extend out of the housing
through respective apertures therein to connect with the clamping-lever arm externally
of the housing, the portions of the housing between these apertures preventing the
clamping lever from passing fully into the housing and potentially causing damage.
Preferably, the clamping lever is formed as a crank-shaped member that is pivotal on
the computer housing adjacent said aperture to form a first class lever. As regards the
screw-threaded means, this is preferably formed by a threaded aperture in the housing
and a threaded bolt engaged in the threaded aperture and bearing against the free end
of the clamping lever arm.
A securing arrangement embodying the invention will now be described, by way of
non-limiting example, with reference to the accompanying diagrammatic drawings, in
which:
- . Figure 1
- is a perspective view of a known plug-in expansion card for a computer;
- . Figure 2
- is a perspective view of the inside of a part of a computer housing showing a known structure for mounting expansion cards,
- . Figure 3
- is a perspective view similar to Figure 2 but showing two expansion cards of the Figure 1 form in a mounted position;
- . Figure 4
- is a perspective view of the inside of a part of a computer housing showing another known arrangement for mounting expansion cards;
- . Figure 5
- is a perspective view of one side of a clamping lever of a embodiment of the invention;
- . Figure 6
- is a perspective view of the other side of the Figure 5 lever;
- . Figure 7
- is a perspective view of the outside of part of a computer housing adapted to receive the clamping lever of Figures 5 and 6; and
- . Figure 8
- is a perspective view similar to Figure 3 but illustrating the operation of the clamping lever of Figures 5 and 6 for clamping two expansion cards of the Figure 1 form on a housing of the Figure 7 form.
Figures 5 to 8 illustrate, on an enlarge scale as compared to Figures 1 to 3, an
embodiment of the invention for securing expansion cards within a computer housing.
According to this embodiment, the fixing screws 19 (see Figure 3) are replaced by a
clamping lever 22 which is fixed in position by a single, externally-accessible, screw
member 25.
More particularly, and with reference to Figures 5 and 6, the clamping lever 22
comprises a crank-shaped metal member formed with an arm 24 that expands out into
four fingers 26. The Fingers 26 have bent-over end portions. An externally-threaded
member 25 is held captive in the free end of the arm 24 and is provided with a knurled
head.
The fingers 26 of the clamping lever 22 are intended for insertion through respective
apertures 32 formed in a computer housing 31 (see Figure 7) adjacent an expansion-card
bridge 34 similar to the mounting bridge 16 of Figures 2 and 3. With the fingers
26 inserted in the apertures 32, the threaded member 25 can screw-threadedly engage
in a threaded aperture 33 formed in the housing 31. The head of the threaded member
25 and the arm 22 lie outside the housing 31 enabling a user ready access to the head
of the threaded member 25. As a user tightens up the threaded member 25 to approach
the free end of the arm 24 towards the housing 31, the clamping lever 22 executes a
pivoting action on the housing about an axis lying generally along the line of the edges
of the apertures 32 nearest the aperture 33. This pivoting action moves the end portions
of the fingers 26 towards the mounting bridge 34. As a result, the fingers 26 can be
used to clamp expansion cards 10 or blanking plates 20 in position on the mounting
bridge 34 as is illustrated in Figure 8. The bent-over end portions of the fingers 26
serve to trap the mounting plates 12 of the cards 10 and/or the blanking plates 20
against the bridge 34 of the housing 31.
This arrangement thus enables a single clamping lever to be used to secure in position
four user-installable units (in Figure 8 the four units are constitued by two expansion
cards and two blanking plates). The clamping lever itself is fixed by a single screw 25
that is readily accessible to the user. There is a little risk of either the fixing screw 25
or the clamping lever 22 falling into the interior of the housing, the lever 22 being
prevented from entering fully into the housing by the portions of the housing located
between the apertures 32.
It will be appreciated that many variants are possible to the illustrated embodiment. For
example, the number of clamping fingers 26 can be varied and, indeed, the clamping
lever may only have one such finger where there is only one user-installable unit to
secure in position. Furthermore, the user-installable unit is not restricted to being a
expansion card and may, for example, be a disc drive unit which it is wished to secure
in position up against the computer housing.
As the clamping lever 22 is formed of metal, it is facilitates earthing of the mounting
plates 12 and/or of the blanking plates 20 on the computer housing 31.
The screw-threaded arrangement may be varied from that illustrated provided that a
first one of the threaded members remains in force-transmitting relation with the
housing 31 and a second one of the threaded members remains in force-transmitting
relation with the arm 24 of the clamping lever, and provided also that one of these
threaded members remains externally accessible for user operation. Thus one possible
alternative arrangement would be to provide the housing 31 with a externally-projecting
threaded stud that passes through an aperture in the arm 24, this stud then
being engaged by a knurled nut bearing against the arm 24. In the illustrated
embodiment of the invention the clamping lever 22 forms a first class lever, that is,
one in which its fulcrum is positioned between the load (here, the clamping end
portions of the fingers 26) and the point of force application (the point at which the
head of the threaded member 25 contacts the arm 24). By appropriate design, it would
be possible to change the class of the clamping lever.
